In the Angular-Camp of 2016 july there was an interest about testing but not talks about, because of this, I was requested by the organizers to do some kind of talk to introduce testing.
Because I already had some experience and previous material I agree to do it.
As material I used a plnkr from a teaching session with my costumers, and also some of the marvelous slides of Miško Hevery of the hot wo write hard code to test presentation.
It was a completely success and they asked for more. Later, in other meetups, I presented the formalization and continuation of this talk.
